Besides suggestions of Ram Prakash Sharma suggestions which are all very good and even i follow like looking at the rising sun for five minutes till it is red ( tratak Kriya every morning), washing eyes with tripala water, eating Amla in any form. I would like to add two more tips:

1) Apply pure Mustard oil ( Kachi Ghani not refined) on both the foot thumbs before sleeping you can even apply the same oil on the base of both feet just before sleeping.

2) The pressure point for both the eyes is the ( V ) point directly below index finger and the middle finger , press the point for five minutes any time and multiple times in a day ( both Hands).
